Outcome

Jean-Marc Denis wanted a little game to help a daughter learn a few Japanese words before a family trip to Japan. Denis says Claude made it real in under an hour, with images from Higgsfield and sounds from ElevenLabs via their command-line tools. The video's opening frame shows a tablet app with four sections, labelled in French: Imagier, Trouve le mot, Memory and Album d'autocollants.

The source didn't share its exact prompt, so we wrote this from what it describes.

What the prompt labels mean

Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points.

Goal: Build a simple game that helps my child learn a few words in a language before we travel.

What I can give you (ask for whatever's missing):
- The language and the words or topics to cover: [WORDS]
- My child's age and the language the menus should be in: [AGE AND MENU LANGUAGE]
- The device it should run on: [DEVICE]

Rules:
- Keep it small: a picture dictionary, a find-the-word game and a memory game are enough to start.
- Show each word with a picture, the word in the target script and a simple pronunciation, and play its sound.
- Check each translation and pronunciation and flag any you're not sure of, so I can confirm with a native speaker.
- Big buttons, no ads, no accounts and no internet needed once installed.
- Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify.

Output: A working app I can open on the device, with the word list in one file I can edit.

You'll know it worked when: my child can play it alone and remembers some of the words by the trip.

Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.
